¿(Está/Es) Difícil?: Variable Use of Ser and Estar by Heritage Learners of Spanish

The current study examines variation in copula selection in Spanish by looking at the written productions of three groups of language learners in the United States, including heritage learners, those with English as an L1, and international students with English as an L2. Research on copula variation in Spanish has pinpointed several key linguistic and social factors that influence selection; this study aims to apply these findings to heritage learners in order to determine how their acquisition differs from that of non-native language learners. This analysis used the COWS-L2H corpus of Spanish from the University of California, Davis. Examining over 8000 tokens of [adjective + copula] constructions in variable contexts where both ser and estar were used, the study tracks how linguistic and extralinguistic factors condition copula selection within the three learner groups and how these results compare to previous findings. Seven factors were predictive of copula selection: resultant state, frame of reference, adjective class, experience with study abroad, essay prompt, student age, and course level. Heritage learner copula use was found to be governed by a different set of predictors than that of learners, hinting at the variable motivations and backgrounds that influence use and reflect the identity goals of these speakers.
